Staffordshire Bull Terrier
The Staffordshire Bull Terrier, also called the Staffy or Stafford, is a purebred dog of small to medium size in the terrier group that originated in the northern parts of Birmingham and in the Black Country of Staffordshire, for which it is named. They descended from 19th-century bull terriers that were developed by crossing bulldogs with various terriers to create a generic type of dog generally known as bull and terriers. Staffords share the same ancestry with the modern Bull Terrier, although the two breeds developed along independent lines, and do not resemble each other. Modern Staffords more closely resemble the old type of bull terrier, and were first recognised as a purebred dog breed by The Kennel Club of Great Britain in 1935. Within the broad sweep of dog history, the story behind the modern Stafford is rather brief and somewhat confusing because of the multiple aliases attached to these dogs in centuries past, such as the "Patched Fighting Terrier", "Staffordshire Pit-dog", "Brindle Bull", and "Bull-and-Terrier". Similar crosses also had aliases such as half-and-halves and half-breds. Blood sports such as bull-baiting and bear-baiting were outlawed with the passing of the Cruelty to Animals Act 1835 by Parliament, making it illegal to bait animals but promoting the matching of dogs against each other. Dog breeders migrated away from the heavier bulldogs, and introduced terrier blood into their crosses for gameness and agility. These bull and terrier crosses produced the ancestral breeding stock that, over the course of decades, evolved into the modern conformation show dogs we know today as the Staffordshire Bull Terrier and the Bull Terrier. It was shortly before the American Civil War that immigrants from Great Britain brought their bull and terrier crossbreeds into the U.S. They became the ancestral progenitors of the American Staffordshire Terrier (AmStaff), Miniature Bull Terrier, Boston Terrier, and American Pit Bull Terrier.

What to Know Before Buying a Staffordshire Bull Terrier
Finding a responsible Staffordshire Bull Terrier breeder requires more than browsing classified ads or responding to social media posts. The USDA requires any breeder who sells dogs commercially — especially those selling online or through third-party dealers — to hold a federal license and submit to regular inspections. A legitimate breeder should be willing to provide their USDA license number, invite you to visit their facility, and show you where the animals are housed and socialized.
Before committing to a purchase, ask the breeder for veterinary health records, vaccination documentation, and any genetic testing results relevant to the Staffordshire Bull Terrier. Reputable breeders will also ask you questions in return — about your living situation, experience with animals, and ability to provide long-term care. A breeder who asks no questions and is eager to ship an animal immediately is a significant red flag.
Use the search tool below to check whether any USDA-licensed facilities breeding Staffordshire Bull Terriers appear in our database. If they do, review their inspection history carefully. Look for patterns of violations, pay attention to severity levels, and compare their compliance grade with other breeders in the same state. This due diligence takes minutes and can save you from supporting a facility with documented animal welfare problems.
